Abstract: 1,179,412. Door handle units. WEST ALLOY DIECASTINGS Ltd. 20 Jan., 1967, No. 47083/69. Divided out of 1179411. Heading E2A. A handle unit for operating door bolts 18a comprises a handle 4a having a stem 3a which may be held in the retracted position shown by automatically-fastening means so that the handle 4a is located in a closely fitting recess formed by a surround 6a, spring means for ejecting the handle from the recess on releasing the fastening means and stop means for halting the spring-ejection of the handle when the latter reaches an intermediate position clear of the recess, so that the handle can be gripped and pulled manually from this intermediate position into its fully projected position, in which it can be turned for operating the bolts. As shown, the automatically-fastening means comprises a spring-loaded bolt 24a projecting from the handle stem 3a to engage behind the end of a housing 2a. Operation of a barrellock 5a retracts the bolt 24a so that the latter can enter a longitudinal groove 2b formed in housing 2a. A spring 22a ejects the handle and bolt 24a. moves along groove 2b until a collar 35 abuts the end face of a sleeve 30 to determine the intermediate position. The sleeve 30 is axially slidable over housing 2a, interengaging lugs and grooves (not shown) limiting this sliding movement. Thus, the handle may be pulled from the intermediate position to its fully projecting position, sleeve 30 being moved to the left from the position shown. On reaching the fully projected position, the bolt 24a may enter a lateral extension (not shown) of groove 2b thus permitting turning of the handle.

Title: Method and apparatus for winding predetermined lengths of elon gate material onto reels spools or bobbins
IPC: B65H54/28
Filed: 1971-10-11
Abstract: 1359059 Continuous winding; counting predetermined lengths SCHWERMASCHINENBAU-KOMBINAT ERNST THALMANN MAGDEBURG VEB 11 Oct 1971 47262/71 Headings D1F and D1J An apparatus for winding predetermined lengths of filamentary material has two reels 1, 2 disposed in parallel relationship, traverse means 3 that can serve first one reel and then the other, and a length measuring device 28 for producing signals on predetermined lengths being reached, said signals being used to vary the traverse stroke. Thus if reel 1 is being used, stop devices 16, 22 initially control the traverse such that the full width of the reel is covered with material. On the first signal being emitted by the measuring device 28 stop device 22 is retracted and stop device 21 is moved to an operative setting, the effect of this being to cut down the length of traverse to 50% of the width of the reel. On a second signal being emitted by the measuring device 28 stop device 21 is retracted and stop device 20 is moved to an operative setting, the effect of this being to cut down the length of traverse to 25% of the width of the reel. On yet a further signal being emitted by the measuring device 28 the filamentary material is moved by a roller 5 into and beyond a plane 37 where it is cut and the material 29 is transferred to reel 2 where a fresh winding begins. At this stage the traverse mechanism 3, 4, 36 moves to the broken line setting. Limit switches 7, 8, 9, 10 control the setting of a roller 6 associated with reel 1. Limit switches 11, 12, 13, 14 control the setting of the roller 5 associated with reel 2.

Title: Methylvinylpolysiloxanes
IPC: C07F7/21
Filed: 1962-12-18
Abstract: The invention comprises compounds of the formula <FORM:0980106/C3/1> where n is 0 or 1.  They are prepared by the reaction of tetraphenyldisiloxane diol-1,3 or hexaphenyltrisiloxane diol-1-5 with a methyl vinyl dihalosilane, in the presence of a hydrogen halide acceptor, e.g. a tertiary amine, in particular pyridine. The reagents are dissolved in an inert solvent, e.g. tetrahydrofuran, n-hexane, xylene, ether or toluene.  The hydrohalide precipitate is removed, then the solvent, and the product is recrystallized.  Polymers containing recurrent units <FORM:0980106/C3/2> where n is 0 or 1, are prepared by heating the compounds I alone at 250-350 DEG  C., or, preferably, with a catalyst at 75-125 DEG  C. A suitable catalyst is a 0.01-1% solution of KOH in octamethylcyclotetrasiloxane, amounting to 10-100 p.p.m. of KOH in the monomer. Copolymers can be made in the same way from mixtures of compounds (I) with themselves or other cyclopolysiloxanes, such as those of Specifications 980,101, 980,102, 980,103, 980,104, 980,105 and 980,107, 980,108, 980,109. Homopolymers and copolymers containing units (II) can be cured by conventional means, e.g. with free radical (e.g. peroxide or diazo) curing agents, or by irradiation, e.g. with 50,000 to 20,000,000 eV electrons. Fillers may be added before cure, if required, and may suitably be silica (aerogel, fumed, precipitated), TiO2, FeO3, Cr2O3, CaCO3, CaSiO3, CdS, lithopone, carbon black, asbestos, talc, glass fibres. The examples describe the preparation, polymerization, and cure to silicone rubbers, of both the compounds (I) and the preparation and cure of copolymers of the trisiloxane (I) with 1,1-dimethyl - 3,3,5,5 - tetraphenylcyclotrisiloxane.
